Definitions

  • logs containing a predetermined quantity of a wound web material are produced in rapid sequence by rewinding machines. These logs usually have a much greater axial length than the length of the finished products, typically rolls of toilet paper or kitchen towels. The logs thus produced must therefore be handled further to be cut into rolls of smaller length and then packaged in packs of plastic film, paper, cardboard or the like. These handling operations require the tail end of the log to be stably fastened to the log, to prevent accidental unwinding of the web material, both during the steps to cut it into rolls and during the subsequent packaging steps.
  • GB-A-1,009,697 discloses a method and a device that fastens the tail end of a log of web material without glue.
  • This system provides for application of a liquid, for example water, to the wound log and embossing with a punch that acts orthogonally to the log, at the tail end on the area in which the liquid was applied.
  • the combination of the embossing pressure and of the liquid causes ply-bonding between the tail end and a plurality of underlying layers, i.e. turns, of web material.
  • This system is ineffective as fastening is not reliable, as it is impossible to apply sufficient pressure to the web material without damaging the log.
  • the invention provides for a method to close the tail end of a log of web material wherein the tail end is secured to the log with mechanical ply-bonding.
  • the tail end is fastened mechanically to a portion of web material of the outermost turn of the log.
  • the method comprises the steps of:
  • the log R with the tail end L mechanically fastened to the fold F is then discharged from the machine along a delivery chute 110 by means of the continuous flexible member 19 which, having performed mechanical ply-bonding of the tail end, starts to move again to control rolling and discharge of the closed log R.
  • roller 205 positioned under the log R is stopped and retains the web material in contact therewith, while rotation of the log R above caused by the tailstocks M (which in this case are motorized) loosens the last turn of web material making said last turn slide on the layer of web material that remains adhering to the roller 205 as a result of the high friction coefficient of the coating of this roller.
